TDTF vs VTIP

TDTFBNorthern Trust iBoxx 5-Year Target Duration TIPS ETF

VTIPAVanguard Short-Term Inflation-Protected Securities ETF

In short

TDTF Most TIPS funds let their interest-rate sensitivity drift as bonds age. TDTF pins it: a monthly-rebalanced index built to hold modified adjusted duration near five years, for 0.18% net of a waiver through March 1, 2027.

VTIP Inflation protection without the long-bond whiplash. VTIP holds only Treasury TIPS maturing inside five years, so CPI does most of the driving and rate swings do less of it, for three basis points a year.

Stated mandate

TDTF The Fund seeks to track the price and yield performance of the iBoxx 5-Year Target Duration TIPS Index before fees and expenses.

VTIP Tracks a benchmark measuring the investment return of U.S. Treasury inflation-protected public obligations with remaining maturities under five years.

Why people hold it

• TDTF The index targets a modified adjusted duration of roughly five years and rebalances monthly, drawing from TIPS maturing in three to twenty years.sec.gov
• Hugging the index is the entire job here, and on that measure it has been one of the stronger implementations in the TIPS group.
• Listed in 2011 under Northern Trust's FlexShares brand, it is a multi-billion-dollar fund with moderate trading volume.
• The holdings are plain US Treasury TIPS, whose principal and interest payments are tied to an official inflation measure.sec.gov

• VTIP Three basis points a year, against a 0.12% median for Treasury bond ETFs in its group. Vanguard's at-cost setup shows up right in the fee line.vanguard.com
• TIPS principal ratchets with CPI, and the under-five-year maturity cap keeps duration short, so rate moves land lighter here than in full-curve TIPS funds like SCHP.vanguard.com
• Open since 2012 and now a multi-billion-dollar, actively traded fund that owns Treasury paper directly. Plain index rules, no swaps, no credit detours.

Worth knowing

• TDTF 0.18% net of a waiver through March 1, 2027 sits above the category median; broad peers SCHP and VTIP charge 0.03%, but let duration drift with their maturity buckets.
• Payments move with inflation accruals, so cash arrives on an irregular schedule rather than a steady monthly rhythm.sec.gov
• Targeting duration holds the dose of interest-rate risk steady, it does not remove it. Real-yield swings still show up in the price.sec.gov

• VTIP Short maturities cut both ways: less sensitivity to rates, and less exposure to shifts in long-run inflation expectations than a full-maturity TIPS fund such as SCHP.
• Income rides on CPI accruals, so the quarterly payout moves around rather than arriving as a steady coupon.
• This is one narrow slice of one market, short US Treasury TIPS, not a diversified bond portfolio.
